如何将冒号分割的最后两列加上双引号？

1. 如将 4:1:0.71:D01C:054301020201 变为 4:1:0.71:"D01C":"054301020201"

复制代码

waker

sed 's/\([^:]*\):\([^:]*\)$/"\1":"\2"/' urfile

关阴月飞

1. awk 'BEGIN{FS=OFS=":"}{$NF="\042"$NF"\042";$(NF-1)="\042"$(NF-1)"\042"}1' urfile

复制代码

1. [root@localhost ~]# cat i
   
2. 4:1:0.71:D01C:054301020201
   
3. [root@localhost ~]# awk 'BEGIN{FS=OFS=":"}{for(i=NF;i>=NF-1;i--)$i="\""$i"\""}1' i
   
4. 4:1:0.71:"D01C":"054301020201"
   
5. [root@localhost ~]#

复制代码

reyleon

1. awk -F: -vOFS=: '{for(i=0;i<2;i++)$(NF-i)="\""$(NF-i)"\""}1'

How about this way that easy to know what you want

$ echo "4:1:0.71:D01C:054301020201" | sed -r 's/:(\w+):(\w+)$/:"\1":"\2"/'
4:1:0.71:"D01C":"054301020201"

$ echo "4:1:0.71:D01C:054301020201" | perl -ape 's/:(\w+):(\w+)$/:"\1":"\2"/'
4:1:0.71:"D01C":"054301020201"

perl的a参数多余了~

Yes, I see and thank you!!!
Usually I use -lane and -lape

BTW, would you like this to use awk that easy to know what you want
easy to know NF-2 with last two items, and use Q to instead of the  double quote marks (")

$ echo "4:1:0.71:D01C:054301020201" | awk -F: -vOFS=: -vQ='"' '{for(n=NF-2;n++<NF;)$n=Q $n Q}1'
4:1:0.71:"D01C":"054301020201"

确实可以精简一些~
